Inspired by a crash in Times Square Thursday that left one person dead and 22 others injured, supporters of the Islamic State militant group (ISIS) has threatened similar vehicle attacks on the New York City tourist hub.

In an incident believed to be unrelated to terrorism, a driver plowed through crowds in the heart of the country’s most populated city. The suspect was charged with second-degree murder, 20 counts of attempted murder and five counts of aggravated vehicular homicide, police said.

ISIS has claimed responsibility for a series of vehicle attacks in Europe in recent months, including in Nice, Berlin, London and Stockholm. A student who rammed his car into a group of people before charging at passerby with a knife at Ohio State University last November was also inspired by ISIS, authorities believe.

On Thursday, a new video released by ISIS showed a purportedly American fighter calling for Americans to carry out knife and vehicle attacks on home soil. In the 44-minute video, photos were shown of multiple locations in the United States, including Times Square, the Las Vegas Strip and banks in Washington D.C.

A bearded fighter using the name Abu Hamza al-Amriki specifically mentioned knife attacks and running non-believers over with vehicles before calling for Americans to wage jihad in the U.S.

Al-Amriki translates as “the American” and also was the name of the last alleged U.S. fighter to appear in an ISIS video, Abu Isma’il al-Amriki, who praised the gunman who killed 49 people inside a gay nightclub in Orlando last June. He added that America was at war “with all the true and sincere Muslims around the world.”

The new video also showcased a haul of new weapons at ISIS’s disposal, including drones, rocket-propelled grenade launchers, video-equipped guided missiles and shoulder-launched surface-to-air missiles.
